According to the domestic application of conductor with reinforced core of carbon fiber in recent years, the line type of conductor with reinforced core of carbon fiber was recommended. Through the calculation and analysis of 220 kV transformation line reconstruction project and 500 kV new line construction project, the technical and economic comparison between alumtnum conductor with reinforced core of carbon fiber (ACCC) and aluminum conductor steel reinforced (ACSR) was investigated for other transformation line reconstruction projects and new line construction projects. Finally, this paper analyzed the composition of price and the condition of popularization and application for ACCC.
